[0001] The utility model relates to a wire reel for electrical threading for wire reel, is used for wire reel when electrical threading belongs to wire reel technical field. BACKGROUND
[0002] Electrical threading refers to the process of threading conductors such as wires and cables through pre-installed pipes (such as PVC pipes, metal pipes), wire slots, or bridge frames in buildings or electrical systems, and connecting them to electrical equipment such as distribution boxes, switches, outlets, and lamps.
[0003] In electrical threading construction, the wire reel for electrical threading is a special tool for storing and releasing wires / cables, which can effectively prevent cable entanglement, knotting or damage, and improve threading efficiency and construction quality. It can prevent cables from being scratched by the ground during dragging. It can prevent cables from twisting and knotting, reducing the mechanical stress on the internal conductors. By rotating the cable, it reduces the manual pulling resistance. It can fix the position of the reel and keep the work area clean.
[0004] In electrical threading construction, it is common to simultaneously thread multiple cables. This operation is usually aimed at scenarios that require parallel laying of multiple wires or cables (such as multi-loop power supply, weak current system wiring, etc.).
[0005] The existing wire reel is designed for simultaneous threading of multiple wires, but it has the following technical problems:
[0006] The existing wire reel for electrical threading generally uses multiple single-axis wire reels placed on the ground to achieve simultaneous threading of multiple wires, which not only requires a large amount of space, but also makes it difficult to control multiple single-axis wire reels simultaneously, resulting in low threading efficiency. Practical new type content
[0007] The utility model aims at providing a wire reel for electrical threading, which solves the problem of low threading efficiency caused by the need for a large amount of space and the difficulty in simultaneously controlling multiple single-axis wire reels in the existing wire reel.
[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0009] The utility model provides an electric wire threading pay-off reel, comprising a support, a plurality of pay-off drum structures are arranged on the support in a circumferential direction of a circle with a point on the support as a center, and a rotating structure is arranged on the support to drive the plurality of pay-off drum structures to rotate synchronously.
[0010] Further, the support comprises a base plate, a support rod oppositely arranged on the base plate, a mounting plate arranged on the support rod, and a plurality of rotating holes arranged at equal intervals in a circumferential direction of a circle with a center of the mounting plate as a center.
[0011] Further, the pay-off drum structure comprises a rotating shaft matched with the oppositely arranged rotating hole in rotation, an I-shaped cylinder arranged on the rotating shaft and limited by the mounting plate, and a driven gear arranged on the rotating shaft at least on an outer side of the mounting plate.
[0012] Further, the I-shaped cylinder is provided with at least one wire clamping groove.
[0013] Further, the rotating structure comprises a main rotating shaft rotatably arranged at the center of the two mounting plates, a limiting block arranged on the main rotating shaft and in contact with the outer sides of the two mounting plates, and a driving gear arranged on the main rotating shaft at one side of the driven gear and matched with each driven gear.
[0014] Further, at least one driving gear is provided with a rotating handle; or / and
[0015] The base plate is provided with a support plate, and the support plate is provided with a rotating motor connected with the main rotating shaft.
[0016] Further, the base plate is provided with a limiting structure for limiting and guiding the wires on each pay-off drum structure.
[0017] Further, the limiting structure comprises two limiting plates oppositely arranged, and a plurality of mounting hole groups with the same number as the pay-off drum structures are oppositely and equally arranged on each limiting plate in a height direction of the limiting plate, each mounting hole group comprises two mounting holes arranged at intervals, and an I-shaped limiting and guiding shaft is arranged on the mounting holes oppositely arranged on the two limiting plates.
[0018] Compared with the prior art, the utility model has the advantages that:
[0019] Firstly, the utility model effectively utilizes the horizontal and vertical space by arranging a plurality of pay-off drum structures in a circumferential direction of a circle with a point on the support as a center, which not only effectively avoids the problem of large space requirement for simultaneously threading a plurality of wires by placing a plurality of single-axis pay-off reels on the ground to simultaneously pay off the wires, but also simultaneously drives the plurality of pay-off drum structures to pay off the wires by the rotating structure, which is beneficial to wire paying off and improves the threading efficiency.
[0020] Second, the bracket structure in this utility model is simple and facilitates the installation of multiple wire feeding drum structures and a rotating structure that cooperates with the wire feeding drum structure.
[0021] 3. The wire feeding drum structure in this utility model is rotated and engaged with the rotating hole on the mounting plate through the rotating shaft, and the wire is fed out by winding the wire on the I-shaped drum body. The two sides of the I-shaped drum body are limited by the mounting plate, which firstly prevents the wire feeding drum structure from moving back and forth along the length direction when it rotates. The driven gear on the rotating shaft is convenient to cooperate with the rotating structure, so as to facilitate the rotating structure to drive multiple wire feeding drum structures to rotate synchronously.
[0022] Fourth, this utility model has at least one wire-holding groove on the I-shaped cylinder to facilitate the holding of the wire end, so as to fix both ends of the wire, avoid the wire from scattering during the unloading process, and prevent the initial wire end from being difficult to fix when the wire is wound on the I-shaped cylinder.
[0023] V. The rotating structure in this utility model fixes the main rotating shaft on the bracket through a limiting block to prevent it from moving back and forth along the length direction during rotation. At the same time, through the meshing of the driving gear and each driven gear, when the driving gear rotates, it drives the main rotating shaft to rotate in coordination with the mounting plate. Each driven gear also rotates in coordination with the mounting plate. The driven gear drives the I-shaped cylinder on the rotating shaft to rotate to simultaneously feed multiple wires and wind the initial wires. The operation is convenient and improves the efficiency of feeding and threading.
[0024] VI. This utility model has a rotating handle on the drive gear, which facilitates manual rotation of the drive gear. The rotating motor is matched with the main shaft to facilitate the rotation of the drive gear by the rotating motor, so as to realize automatic take-up or unwinding of the line.
[0025] VII. The limiting structure in this utility model is conducive to threading each wire through the I-shaped limiting guide shafts on each mounting hole group. By being limited by the I-shaped limiting guide shafts, the wires are prevented from easily crossing, which would affect the laying or threading of the wires. Attached Figure Description

[0044] Example 1
[0045] To address the issue of low threading efficiency when simultaneously feeding and threading multiple wires using existing wire feeding reels, which typically employ multiple single-axis wire feeding reels placed on the ground, this method not only requires significant space but also makes it difficult to control the feeding of multiple reels simultaneously. Figures 1-8 As shown, an electrical wire feeding reel is provided, including a bracket 1, multiple wire feeding drum structures 2 that are rotated on the bracket 1 with a point on the bracket 1 as the center and along the circumference of the circle at the center, and a rotating structure 3 that is mounted on the bracket 1 to drive the multiple wire feeding drum structures 2 to rotate synchronously.
[0046] In practice, the rotating structure 3 drives multiple pay-off drum structures 2 to rotate, so that each line is collected on the pay-off drum structure 2. Then, the pay-off reels are transported to the threading position, that is, the support is placed on the ground. One construction worker operates the rotating structure 3 to drive the pay-off drum structures 2 to pay off the line, while another construction worker performs the threading operation on the paid-off line. Of course, a single person can pay off the line and then perform the threading operation. In this embodiment, multiple pay-off drum structures are set up by rotating around a point on the support along the circumference of the circle at the center. This effectively utilizes the horizontal and vertical space (as shown in the figure, it saves space compared to placing them all on the horizontal plane). This not only effectively avoids the problem of large space requirements when multiple single-axis pay-off reels are placed on the ground to pay off multiple lines at the same time, but also improves the efficiency of threading by driving multiple pay-off drum structures to pay off lines simultaneously through the rotating structure.
[0047] Example 2
[0048] Based on Embodiment 1, the bracket 1 includes a base plate 4, a support rod 5 disposed on the base plate 4, and a mounting plate 6 disposed on the support rod 5. Multiple rotating holes 7 are evenly spaced along the circumference of the mounting plate 6 with its center as the center. The mounting plate can be cross-shaped as shown in the figure, which uses less material; of course, it can also be circular, square, or star-shaped. The bracket structure in this embodiment is simple and facilitates the installation of multiple pay-off drum structures and rotating structures that cooperate with the pay-off drum structures. Of course, in practice, other structures are not excluded.
[0049] Example 3
[0050] Based on Embodiment 2, the pay-off spool structure 2 includes a rotating shaft 8 that rotatably engages with a rotating hole 7, an I-shaped cylinder 9 mounted on the rotating shaft 8 and limited by a mounting plate 6, and a driven gear 10 mounted on at least one outer side of the rotating shaft 8. The pay-off spool structure rotatably engages with the rotating hole on the mounting plate via the rotating shaft, and pays off the line by winding the line on the I-shaped cylinder. The two sides of the I-shaped cylinder are limited by the mounting plate to prevent the pay-off spool structure from moving back and forth along its length when rotating. The driven gear on the rotating shaft facilitates engagement with the rotating structure, allowing the rotating structure to synchronously drive multiple pay-off spool structures to rotate.
[0051] At least one wire-holding groove 11 is provided on the I-shaped cylinder 9. The purpose of providing at least one wire-holding groove on the I-shaped cylinder is to facilitate the holding of the wire end, so as to facilitate the fixation of both ends of the wire, avoid the wire from scattering during the unwinding process, and prevent the initial wire end from being difficult to fix when the wire is wound on the I-shaped cylinder.
[0052] The rotating structure 3 includes a main rotating shaft 12 rotatably mounted at the center of the two mounting plates 6, a limiting block 13 mounted on the main rotating shaft 12 and in contact with the outer sides of the two mounting plates 6, and a driving gear 14 mounted on the main rotating shaft 12 on one side of the driven gear 10 and cooperating with each driven gear 10. The rotating structure fixes the main rotating shaft to the bracket through the limiting block to prevent it from moving back and forth along its length direction during rotation. At the same time, through the meshing of the driving gear and each driven gear, when the driving gear rotates, it drives the main rotating shaft to rotate and cooperate with the mounting plates. Each driven gear also cooperates with the rotation of the mounting plates. The driven gear drives the I-shaped cylinder on the rotating shaft to rotate, so as to simultaneously release multiple wires and wind the initial wires. The operation is convenient and improves the efficiency of releasing and threading wires.
[0053] At least one drive gear 14 is provided with a rotating handle 15; or / and the base plate 4 is provided with a support plate 16, and the support plate 16 is provided with a rotary motor 17 connected to the main rotating shaft 12.
[0054] Whether or not a protective sleeve is installed on the I-shaped cylinder 9 to prevent damage to the wire depends on the material.
[0055] In practice, when it is necessary to reel in the wire, the head end of each wire is first secured in the wire-holding groove 11 on the corresponding I-shaped cylinder 9. The drive gear 14 is rotated in the reverse direction by manually operating the rotating handle 15, or the drive gear 14 is rotated in the reverse direction by the rotating motor 17 driving the main shaft 12, which in turn drives the driven gears 10 to rotate. The rotation of the driven gears 10 drives the I-shaped cylinder 9 to rotate, thus reeling the wire in onto the I-shaped cylinder 9. Conversely, when it is necessary to unload the wire, the tail end of each wire is first removed from the wire-holding groove 11. The drive gear 14 is rotated in the forward direction by manually operating the rotating handle 15, or the drive gear 14 is rotated in the forward direction by the rotating motor 17 driving the main shaft 12, which in turn drives the driven gears 10 to rotate. The rotation of the driven gears 10 drives the I-shaped cylinder 9 to rotate, thus unloading the wire from the I-shaped cylinder 9, which facilitates threading the unloaded wire.
[0056] Example 4
[0057] Based on embodiment 3, the base plate 4 is provided with a limiting structure 18 for limiting and guiding the lines on each pay-off drum structure 2. The limiting structure 18 includes two opposing limiting plates 19. Along the height direction of each limiting plate 19, each limiting plate 19 has a set of mounting holes arranged opposite to and at equal intervals, the same number as the pay-off drum structure 2. Each set of mounting holes includes two spaced-apart mounting holes 20. An I-shaped limiting guide shaft 21 is provided on the opposing mounting holes 20 on the two limiting plates 19. During take-up and pay-off, each line is threaded between the I-shaped limiting guide shafts on each mounting hole set. The limiting effect of the I-shaped limiting guide shafts prevents the lines from easily crossing, thus affecting take-up, threading, or other operations.
[0058] This invention sets different sizes of the pay-off reel according to the thickness of the line. When the pay-off reel is small, the limiting structure can also be used as a convenient handle.
